FUEL ECONOMIZER FOR GAS-FIRED STO'VES AND THE LIKE.

Application filed July 12, 1922. Serial No. 574,588.

To all whom it may concern:

Be it known that HENRY PERCY Evans and HENRY SNowDoN STANDEN, subjectsof the King of Great Britain and Ireland, residing, respectively, atWymston, Vymston Parade, Abbotsford, near Sydney, New South lV-ales,Australia, and Cross Street, \Vaverley, near Sydney aforesaid, haveinvented new and useful Improvements in Fuel Economizers for Gas-FiredStoves and the like, of which the following is a'specification.

This invention relates to fuel economizer apparatus which is usable inconnection with gas-fired stoves and the like.

The apparatus comprises a metal plate which is adapted to be set over agas stove burner or et and to hold thereon in separate positions two ormore pots or similar receptacles to which heat is conveyed from the oneburner or jet. The plate is constructed specially to enable properdistribution of the flame from the burner or jet to the separatereceptacles carried thereon as well as to permit proper positioning ofthe rece tacles on the plate.

eferring to the accompanying drawings, Fig. 1 is a plan view of the topor upperside of the plate, and Fig. 2 a plan view of the bottom or lowerside thereof.

The metal plate is preferably cast, and is of suitable thickness, andits dimensions are such to permit its central portion to overlie a gasburner, whilst the plate is resting on a stove or the like, and thereceptacles to which heat is to be conveyed are resting partly on thecentral portion and the outer portions of the plate and if necessarypartly on the stove or the like. It is preferred to construct the platewith a central circular portion 1 having the arms 2 radiating therefrom,such arms being disposed in relation to the central portion and toadjacent arms, whereby an opening 3 will be provided between each of thesaid arms. The outer ends of the arms 2 are preferably curved. Disposedaround the outer ends of the central portion 1 of the lower face of theplate between the arms 2 are a series of grooves 4; these grooves taperfrom said outer ends. There are also larger grooves 5 at the sides ofthe arms 2 and flanking the grooves 4;. The portions of the central part1 of the plate in which the taper grooves 4t are formed are curved andproject into the openin s 3 between the arms 2.

On the upper face of the plate is a rib; this rib is of largerdimensions at its central part 7 which is located on the portion 1 ofthe plate than the fins 6 which project therefrom and extend partlyalong the arms 2. The said rib and fins are arcuated and serve asabutment stops for the lower edges of pots or similar receptacles, seton the plate for the purpose of having heat trans mitted thereto, aswell as reinforcements for the plate.

In operation, the plate is set on a stove or the like with the centralportion 1 thereof located directly over the gas burner or jet of thestove or the like. If there are three openings 3 provided in connectionwith the plate three pots or similar receptacles to which heat is to beconveyed may then be placed on the plate, the rib 7 and fins 6 servmg asseparating stops for the individual receptacles. Flame from the burneror jet is thus spread by the central portion 1 of the plate and isprojected into the openings 3 and under the receptacles to be heated.The grooves 4t and 5 serve to conduct the flame from the central portion1 of the plate to the individual receptacles, and the heat of the flamefrom the one burner or jet of the stove or the like is thus evenlydistributed to the separate receptacles.

What we claim as our invention and desire to secure by Letters Patentis 1. A fuel economizer for gas-fired stoves and the like consisting ofa metal plate, said plate having a central portion adapted to overliethe flame of a fuel burner, spaced arms radiating from said centralportion and providing openings between said arms, the outer edges ofsaid central portion extending into said openings between said arms andadapted to deflect flame projected onto said central portion from a gasburner under receptacles placed on said plate over said openings.

2. A fuel economizer for gas-fired stoves and the like consisting of ametal plate, a central portion for said plate adapted to be set over agas-burner, a plurality of arms radiating from said centra portion anddisposed in relation thereto and to adjacent arms whereby openings areprovided between said arms, said central portion having at its outeredges located between said arms a series of grooves adapted to deflectflame projected onto the said central portion from said gas burner tothe separate openings between said arms, whereby receptacles set on saidplate over said openings may be separately heated.

3. In a fuel economizer for gas-fired stoves and the like as set forthin claim 1 hereof, the construction in which one face of the metal plateis formed with an arcuate rib and fins serving as a separating stop forreceptacles set on said plate for the purpose of being heated.

4. A fuel economizer for gas-fired stoves and the like comprising ametal plate, a central portion for said plate adapted to be set over agas-burner to serve as a gas distributer, three or more arms projectingfrom said central portion Whose outer edges extend into openingsprovided between each said arms, flame deflecting grooves in said outeredges on one face of said plate, and a fin rib located on the other faceof said plate whose centre is thickened and whose fins extend from saidcentre and along part of said arms whereby saidfin-rib is adapted toserve as a separating sto for individual receptacles placed on sai plateover said openings for the purpose of being heated.

5. In a fuel economizer for gas-fired stoves and the like consisting ofa plate furnished With a central portion and with three or more armsradiating therefrom and disposed in relation to each other and to saidcentral portion whereby an opening will be provided between each saidarms, the combination of a fin-rib located on one face of said plateadapted to act as a separating stop for receptacles placed over saidopenings in said plate and as a reinforcement for said plate.

6. A fuel economizer comprising a central body part adapted to overliethe flame of a fuel burner to cause the deflection of said flame towardthe edge of the body member, arms radiating from said body member, thetop surfaces of said body member and said arms being adapted to supporta plurality of cooking vessels and said arms being arranged in spacedrelation to provide openings thereunder through which the flamedeflected by said body member may issue and play upon the bottoms of thecooking utensils supported over said openings.

In testimony whereof we have signed our names to this specification.
